单击搜索栏后，有人知道如何过度调整变暗的黑色吗？

我在单击取消时遇到问题，tableview 将消耗然后动画消失。
i using this to resize my result tableview.
我用它来调整我的结果表视图的大小。
-(void)searchDisplayController:(UISearchDisplayController *)controller didShowSearchResultsTableView:(UITableView *)tableView {
tableView.frame =fTableView.frame;//CGRectMake(26, 100, 280, 310); //fTableView.frame;
tableView.backgroundColor = [UIColor colorWithRed:243.0/255.0 green:236.0/255.0 blue:212.0/255.0 alpha:1];
}
when clicked on the search bar, gray overlay are full instead of my defined size.
单击搜索栏时，灰色覆盖已满，而不是我定义的大小。

I combined several answers in order to move the dimmed overlay frame.
我结合了几个答案以移动变暗的覆盖框。
1: override UISearchDisplayController class
1：覆盖 UISearchDisplayController 类
@interface MySearchController : UISearchDisplayController
2: override setActive function
2：覆盖setActive函数
- (void)setActive:(BOOL)visible animated:(BOOL)animated
{
[super setActive: visible animated: animated];
//move the dimming part down
for (UIView *subview in self.searchContentsController.view.subviews) {
//NSLog(@"%@", NSStringFromClass([subview class]));
if ([subview isKindOfClass:NSClassFromString(@"UISearchDisplayControllerContainerView")])
{
CGRect frame = subview.frame;
frame.origin.y += 10;
subview.frame = frame;
}
}
}
3: change the xib/storyboard Search Display Controller from UISearchDisplayController to MySearchController
3：将xib/storyboard Search Display Controller从UISearchDisplayController改为MySearchController

I thought the searchDisplayController owned a seperate tableview, so my guess is that you would need to resize that one.
我认为 searchDisplayController 拥有一个单独的 tableview，所以我的猜测是你需要调整它的大小。
Something along the lines of: <yourSearchViewController>.view.frame =self.tableView.frame;
类似的东西： <yourSearchViewController>.view.frame =self.tableView.frame;
or if you don't have it as class variable, in a method which receives it as argument, eg:
或者，如果您没有将其作为类变量，则在将其作为参数接收的方法中，例如：
-(void)searchDisplayController:(UISearchDisplayController *)controller didShowSearchResultsTableView:(UITableView *)tableView {
controller.view.frame = self.tableView.frame;
tableView.backgroundColor = [UIColor colorWithRed:243.0/255.0 green:236.0/255.0 blue:212.0/255.0 alpha:1];
}
Alternativily you might want to subclass it and override its view properties locally.
或者，您可能希望子类化它并在本地覆盖其视图属性。
Hope this helps!
希望这可以帮助！

The UISearchDisplayControllerdoes owns its own tableview which not as easy to tame.
I came across something like this and am still looking for a better solution.
在UISearchDisplayController不拥有自己的tableview这不是那么容易驯服。我遇到了这样的事情，并且仍在寻找更好的解决方案。
-(void)searchDisplayControllerWillBeginSearch:(UISearchDisplayController *)controller
{
[controller.searchResultsTableView setDelegate:self];
CGFloat gr = 12.0;
controller.searchResultsTableView.backgroundColor = [UIColor colorWithRed:gr green:gr blue:gr alpha:0.0];
[controller.searchResultsTableView setSeparatorStyle:UITableViewCellSelectionStyleNone];
CGRect searchTableFrame = CGRectMake(7, 105, 305, 292);
[controller.searchResultsTableView setFrame:searchTableFrame];
}
The above code does sets the background to transparent but seems to silently ignore the frame size.
上面的代码确实将背景设置为透明，但似乎默默地忽略了帧大小。
EDIT:SOLVEDI found the robust solution to this here. This saved my life.
编辑：解决了我在这里找到了强大的解决方案。这救了我的命。
